The most ancient archaeological remains in the area of Iniesta are from the Neolithic and bronze age. In the iberian period, Iniesta was called “Ikalesken” and it had its own money. There are remains of this period, like the necropolis in “Cerro Gil” or the remains of the necropolis at the end of “Barrionuevo” Street. With the romanization, Iniesta was called “Egelasta” but there are no archaeological remains of this period. In the hispanic-muslim period, it was called Yanasta and there is a tower of the old arabic castle, defensive door to access to the fortress of s.XI. The Spanish king Alfonso VII conquered 1186 and promoted the re-population giving privileges.

During the middle ChristianAges, Iniesta went from the hand of royalty to the hands of lords, such as, Don Juan Manuel and the last marquis of Villena. That marquis rebelled against the Catholic King and Queen and the were defeated which caused Iniesta to be independent again in 1476. After that, the queen Isabel I of Castile ordered the walls to be destroyed and the battlements of the castle to be knocked down. From now, Iniesta started living good times and a urbanistic transformation. Thanks to this the town hall was built next to the ancient castle wall, the main square was rebuilt and the church, Franciscan convent, the “Concepción chapel” and “Vadocañas” bridge were built.
